Abstract
The present invention relates to a detonator for exothermic flux, which comprises the following main components with the shares by weight: 100 shares of magnesium powder with 40 meshes to 200 meshes, and 20 shares to 80 shares of cupric oxide or/ and iron oxide with 100 meshes to 300 meshes, wherein iron oxide is any one single component of ferroferric oxide or ferric oxide, or mixtures of any proportion of ferroferric oxide and ferric oxide. The present invention has the advantages of simple components, convenient preparation, low price and economical use. Particularly, the components which are convenient for storage, transportation and use have the advantages of no toxicity or no explosiveness.
Description
Technical field
The present invention relates to a kind of detonator that is used for exothermic welding flux.
Background technology
At present, the detonator that exothermic welding flux is used mainly contains two kinds, a kind ofly is made up of magnesium powder, potassium chlorate, pure copper powder, silicon calcium powder, another kind ofly is made up of iron oxide, aluminium powder, potassium chlorate, potassium bichromate, zinc oxide, glass dust, sulphur, dextrin, ancient glue of winter.All contain potassium chlorate in these two kinds of detonators, potassium chlorate is poisonous and have explosivity, and it and organic matter grind altogether and will set off an explosion; A kind of detonator in back also contains potassium bichromate and sulphur, and potassium bichromate has superpower oxidisability and toxicity, and sulphur has explosivity, and sulphur, potassium chlorate, glass dust combined group achievement are soil system grenades.These detonators exist explosive hidden danger and poisonously are not easy to store, transportation, use.
Summary of the invention
The detonator that is used for exothermic welding flux that provides a kind of safe being convenient to store, transport, use is provided technical problem to be solved by this invention, and the present invention is by the following technical solutions for this reason: it mainly consists of:
100 parts in magnesium powder 40 orders～200 orders
Cupric oxide or/and iron oxide 100 orders～300 order oxygenation efficiency 80%～99.9% 20 parts～80 parts, iron oxide is the arbitrary one-component of tri-iron tetroxide and di-iron trioxide or the mixture of arbitrary proportion,
Above umber by weight.
Because adopt above technical scheme, component of the present invention is simple, preparation is convenient, and inexpensive economy, the effect that especially has are that said components is nontoxic does not have an explosivity, is convenient to store, transportation, uses.
The specific embodiment
| The magnesium powder | 160 orders, 120 grams | 80 orders, 100 grams | 110 orders, 105 grams |
| The cupric oxide iron oxide | 180 orders, oxygenation efficiency 85.7%, 63 gram | 200 orders, oxygenation efficiency 92.6%, 50 grams, 280 orders, oxygenation efficiency 81.5%, 15 gram | 270 orders, oxygenation efficiency 92.1%, 37 gram |
The iron oxide of above embodiment is the arbitrary one-component of tri-iron tetroxide and di-iron trioxide or the mixture of arbitrary proportion, and above embodiment all mixes with commonsense method and gets final product.
Claims (1)
1, a kind of detonator that is used for exothermic welding flux is characterized in that it mainly consists of:
100 parts in magnesium powder 40 orders-200 order.
Cupric oxide is or/and 20 parts-80 parts of iron oxide 100 orders-300 order oxygenation efficiency 80%-99.9%, and iron oxide is the arbitrary one-component of tri-iron tetroxide and di-iron trioxide or the mixture of arbitrary proportion,
Above umber by weight.
